Application led November 28, 1924. Serial No. 752,531.

My invention relates to improvements in ear roots designed to be used on steel con structed cars but may be used for other purposes; and the objects ot my improve ments are, Erst; to provide a vmetal roof which to a. degree flexible; second; to have the parts ot the root laid together without being soldered or otherwise rigidly secured together; third, to make a root' which is easily repaired in sections; forth; to make a root which is absolutely waterproof; litth, to make a root which is applicable to the present standard constrin tion of cars ;V sixth, to maire a root which novel, ches p and durable7 and other features to become apparent from the construction to follow.

ln the construction et railroad car roots which are made of sheet metal it is desirable to have a certain amount ot loosenessor flexibility between the pieces of sheet metal so that the slight twisting or shifting et the car traine will not open the joints between the pieces ol sheet metal or otherwise cause the root to become leaky; it is also desirable to have the construction such that it can be easily repaired; to have the root' waterprootr to have the root applicable to the standard make of cars and to have it light and durable, and all these desirable ieatures are attained by the use of my invention which comprises a plurality of troughs spaced apart extending from one side of the car across the apex ott the roof to the other side of the car and long strips of sheet metal also extending from one side of the car to the other with their bent down edges extending into the said troughs.

To describe my invention so that others versed in the art to which it pertains can make and use the same, I have illustrated it on the accompanying -tour sheets of drawings forming a part of this specification; and in which:

Figure l; is a plan View et a ear roof embodying my invention toreshortened and partly broken away for purposes ot illustration; Fig. 2, is a side elevation ot a. car root' end or diaphragm forming a part of my improved roof; Fig. 3, is a cross sectional view on line 3 3 of Fig. 2, viewed in the direction indicated by the arrows; Fig. d, is a side elevation ot a U shaped trough forming a part of my invention; Fig. 5, is a cross sectional view taken on line 5-5 of Fig. 4; viewed in the direction indicated by the taires on line G-G oi Fig. l, viewed in the direction indicated by the arrows; Fig. 7, is a section taken on line 7 7 of: Fig. l; viewed in the direction indicated by the arrows; Fig. 8, is a sectional view taken on line SWS oi Fig. l, viewediin the direction indicated by the arrows; Fig. 9, is a sectional view taken on line 9*-9 oi' Fig. l, viewed in the direction indicated by the arrows; Fig. l07 is an inverted plan view ot a :fractional part of the root at one of the several U shaped troughs or ribs, enlarged and partly broken away for purposes of il lustration; Fig. ll, is a. sectional'view taken on line ll-ll of F l0, viewed in the direction indicated by the arrows; Fig. l2, is a similar view to Fig. 10; showing a rib next to the end et the car rooif;l+`ig. 13, is a sectional view taken on line 12d-13 ot Fig. l2. viewed in the direction indicated by the arrows; Fig. 14, is a. sectional view taken on line lil-let ot Fig. l, showing how the running boards are secured to the roof; Fig. l5; is a sectional view taken on line lli-15 ot Fig. l, viewed in the direction indicated by the arrows showing the root' resting on the upper frame ol the car and the manner of fastening the same thereto; F 16, is a side elevation of the center root supporting angle foreshortened; Fig. 17; is a similar view of one roof side supporting Z bars; Fig. 18; is a detail sectional view showing how the root' cross ribs it into notches provided in the center roof supporting angle; Fig. 19, is a. similar view ot' one side root supporting Z bar; Fig. 20, is a perspective View of one roof sheet metal plate; Fig. 21, is a perspective view of a roof supporting cross rib; Fig. 22, is a perspective'view o1c a root supporting brace, and Fig. 23, is a sectional view taken on line 23-23 ot Fig. l5, showing the connection between the root cross rib and the supporting Z bar.

Similar reference characters refer to similar parts throughout the several views.

The roof supporting framework comprises ends or diaphragms 25, side Z bars 26 and a central supporting angle 27.. The Z bars 26 are cut away at their ends as seen at 2S in Fig. 17, and are riveted to the diaphragms 25 as seen in Fig. 9, and the angle 27 'has its ends riveted to the diaphragme 25 as seen in Figs 6 and 8, by means ot interposing a short piece of I beam 29. This arrangement permits of very light construe t" and yet suficiently stronrf teisr've the purpose, @he end diaphragme S5 rest on the channels 30 forming the top sills of the ear ends, and the Z bars 26 rest on the angles 31 forming the top sills of the sides ot' the car. sce Figs. 1, 6, 7, 8, 9 and 15.

The Z bars 26 and the angle 27 have their upper edge provided with spaced rectangular notches 32 to receive the U-shaped troughs 33 which extend from one side Z bar to the other` side Z bar and have their ends projecting out a short distance beyond the Z bars, so that water passing down in the troughs will be delivered beyond the side of the car body.

As clearly shown in Figs. 1, 16 and 1T, the notches 32 are equally spaced throughout the length of the roof from one car end to the other car end. so that the sheet metal strips 34 are all of the same width when in proper position having their bent down edges 35 extending into the troughs 33. To strengthen and support the root' sheets 3l I preferablv arrange six rows ot' braces 3G under the sheets 34: and spanning the spaces between the troughs 33 with their bentdown ends 37 extending into the troughs. To lock the sheets 34; and the braces 3G to the troughs 33, Cotter pins 38 are passed through registering perfor-ations in the several parts as clearl;7 shown in Figs. 1() to 13. As will be seen in Figs. 12 and 13, the end troughs 33 are riveted to the end diaphragms 25. )is shown in Figs. G, 7, 15 and 23, the troughs 33 near their ends are secured to the Z bars 26 and the angles 31 by means of bolts 39,

the heads of which i'it snugly in the troughs to prevent the same from turning. and the nuts 40 belou7 the angles 31 are provided with nut locks 41 to prevent the nuts turningr loose.

The running boards 42 are .secured by screws to the saddles 113 which are serurcfl to the central part ot the roof b v means o1 the Z shaped metal straps 114 which are bolted at their upper ends to the saddle and have their lower ends extending into the troughs 33 where they are secured by the Cotter pins 38.

The customary ladder round is shown at 45 and the usual brake wheel is shown at 46.

Having thus fully described in v invention what I claim as new and desire to secure b v Letters Patent of the United States is:-

In a car root in combination. cai-lines, purlincs extending between the carlincs. roof sheets supported upon said carlines and purlines, said carlines being U-shaped in section and haring laterally extending flanges at their upper edges, said pui-lines and .said roof sheets being supported on said laterally extendingI flanges and each havingr depending flanges at opposite edges thereofl extending into said carlines and means .securingr the depending flanges o the said purlines and root sheets to the carlines.

In testimomv whereof I have .signed my name to this specification this 13th day of October, 1924, at Chicago, Illinois.
